Thank you! Can you also change the documentation?

Also, it would be great if you could try to fit the commit message into 50 characters (starting with n-api: ), otherwise somebody can do that while landing.

nit: This is a bit pedantic but we do use 4-space indentation for statement continuations, this can stay as it was.

This is a typo, will fix it

Can the IsConstructCall() methods be deleted?

Remove the extra blank line. I think the linter will complain anyway.

Left some comments. Mainly the doc needs updating.

nit: Since this is C++ code use nullptr

Use REPLACEME instead of a specific version. Whoever does a release will then update it to the correct version. (This will be in some later 8.x release.)

I don't know if it's worth it since n-api is still unofficial, but we could also make a function level changelog entry stating that it was renamed.

Can you remove the curly braces on the if-else.

I think that it is better to be consistent with the rest of the file.

-This API checks if the the current callback was due to a
-consructor call.
+This API return the `new.target` of the construct call. If the current
+callback is not a constructor call, the result equals to `nulltpr`.


Replace "construct" with "constructor" here and above.

Fix grammar: "This API returns the new.target" ... "the result is nullptr."

AIX is known unrelated issue
ARM was problem in building and unrelated.

We are good to land, but I want to make sure we are ready with required changes in wrapper and ported modules before we land.

@mhdawson are you going to check for the required changes? If so, would you mind assigning yourself to the PR?

mhdawson · 2017-09-14T20:15:15Z

Linux failure looks unrelated, opened #15416

mhdawson · 2017-09-14T20:16:34Z

ARM failure said this

ccache: error: x_calloc: Could not allocate 40 bytes

so believe its unrelated as well, opened nodejs/build#884
